变电站在线监测及辅助设备监控系统研究与应用

Research and Application on Line Monitoring and Auxiliary Equipment Monitoring System

智能电网的发展及变电站设备状态检修的全面开展,要求对变电站各种设备进行有效地集中监控。文中通过在变电站建立智能辅助监测终端,采用设备ADP+设备规约库动态统一接入各种辅助监测设备,利用信号变频采样、告警录波等采集策略提取设备运行关键信息,分级冗余存储数据,并采用多点同构的分布式服务架构为变电站运行人员、检修人员以及管理人员提供面向角色的差异化应用服务,提高了对运行设备的实时监测水平,降低了运行检修成本。

With the development of smart grid and the fully operational of substation equipment state maintenance, various equipment of substation is required to monitor in effect. Equipment ADP ＋ device protocol library are used for dynamic unified access various auxiliary monitoring equipment with the help that intelligent auxiliary monitoring terminal is built in substation. The acquisition strategies such as signal frequency sampling and alarm recorded wave are used to extract equipment running critical information and grade redundant storage data. Distributed services architecture with multi-isomorphic is used to provide differentiated application service of oriented role for operating personnel, maintenance personnel and management personnel of substation which improves the level of real-time monitoring of the operating equipment and reduces operating maintenance costs.
